RUBBING MACHINE.

Application filed May 2,

This invention relates to machines for treating fabrics while advancing. the fabric lengthwise of itself, and particularly to machines for treating fabrics in which they undergo a rubbing operation, as in the Edlich Reissue Patent No. 16,388.

The improvements contemplate the endless apron forming a part of means which are coactive to effect the rubbing being supported and adapted to be driven by two rollers and means fordriving these rollers first in one direction and then in the other having driving connection independently of the apron with each roller; in a combination including a fabric-advancing apron and three guides around which the same extends taut and each extending across the apron and two of them maintaining the rubbing stretch of the apron and one of such two being a roller revoluble to advance the fabric, that the third guide shall be shiftable into and out of oblique relation to the other two guides whereby to insure the apron and consequently the fabric running true; in combination, with rotary mechanism including reversible rotary fabric advancing means tosupport the fabric in operative relation to a rubbing means, separate'revoluble core structures .on which the respective ends of the fabric are to be alternately wound up, separate slip-friction disconnective driving connections between said mechanism and the respective core structures, and reversing means for said mechanism operative to establish the driving connection for the thereupon receiving core structure and simultaneously disestablish theconnection for the other core structure, and (in the preferred construction) separate means, controlled by said reversing means, to resist the advance of the fabric and so impose tension thereon; novel means whereby both faces of an advancing fabric may be treated by a liquid or other suitable substance; and a novel form of rubbing roller.

said apron and applying a-liquid to the:

fabric and Figs/10 and 11 show the preferred form of a rubbing roller inside and end elevation.

A frame 1 has vertical uprights 2' afl'ording guides for a frame which maybe vertically ad]usted by turning the cams 4 rest-' ing on rollers 5 journaled on the uprights. Frame 1 and adjustable frame 3 carry two sets of coacting means to perform the rubbing, thus: One includes an apron 7 backed by and extendingaround a group of rollers 6, 6, 6 journaled in frame 1 with a group of rubbing rollers 9, journaled in frame 3,'to coact with saidapron; the other includes an apron 7 backed'by and extending around a group of rollers 9 journaled in "frame 3, with a group of rubbing roller-s journaled in frame 1, to coact with said apron 7 When, as by a'belt 8 extending around pulleys on the 'rollers9 and 8 and a pulley 8 on the hereinafter mentioned 'countershaft .11, these rollers are driven. the fabric A,"which passes between such rollers and'the aprons respectively opposed thereto, will be rubbed sub- 7 stantially as and by means similar to that set' forth in the mentioned Edlich patent. (The apron '7 may also be driven, as with the fabric, by belt 8 being engaged with a pulley on one of the rollers 9.) I

The main drive shaft is indicated at 10. As will hereinafter appear, a countershaft 11 is driven first in one direction and then in the other from shaft 10 through first one and thenthe other of two sets of gears (Fig. 2), in one ofwhich the members12 and 13 are in direct mesh with each other and in the other of which, 14 and 15, the members are connccted or in mesh with an intermediate pinion 16. The driving of the'apron'7 is effected, as willappear, from. the countershaft and it is very important in the present example that the apron should be influenced by whatever drives it the same when it is moving in one direction as when it is moving in the other-thus, it should not be in effect pulled in one direction and pushed in the other-else it will buckle and harmful re sults in the treatment of the fabric will ensue. Hence, both of the rollers 6 and 6 are geared with the countershaft, as by the sprocketand-chain connections 16 and 17, (18 is simply a s]ack-takeup device for chain 17). The roller 6* is not directly carried by the frame 1, but is preferably journaled in a pair of bracket structures 19 which are slidable longitudinally of and on the frame and have tapped into them screws 20 connected by gearing as shown. with a cross-shaft 21, having a hand-wheel 21 for turning it, the screws and cross-shaft being j ournaled in the frame 1 (Figs. 1, 3, 8 and 9) thus the apron 7 may be kept taut.

This apron is controlled by hand against skewing to one side or the other, which it tends to do on account of its considerable width. For this purpose there is the means shown best in Figs. 2, 3 and 4. At 22 is a roller which bears against the lower stretch of the apron and by ball-bearings 23 is ournaled on a shaft 25. This shaft is pivoted at one end at 26 (Figs. 1 and 2) in the frame so as to swing in a horizontal plane, and its other end is longitudinally slotted and received by the forked jawof a slide 27 guided horizontally and lengthwise of the machine in a bracket 28, said jaw having. a stud 29 engaged in the slot of the shaft (Fig. 4). it screw 30 is swivelled in the bracket 2) and tapped into the slide (Fig. 4) and has a hand-wheel 30 for turning it. The attendant, while the machine is operating, watches the progress of the apron and if it skews one way or the other he shifts the shaft 25, by turning the hand-wheel in the appropriate direction, so that the roller tightens the apron'at one side and permits slackening thereof at the other, thus correcting the travel of the apron. So far as I am aware it is new to extend the apron taut around three such guides as 6", 6" and 22 so that two of them maintain a stretch of the apron taut and in operative relation to a coacting rubbing means (as 9) and one of such two is a roller revoluble to advance the apron and to provide for the shifting of the third guide into and out of oblique relation to the other two.

There is a beam at each end of the machine on which the fabric may be wound up and from which it may be unwound. (Since the fabric is advanced by the apron 7 at constant speed and the winding-up on either of these beams, if their speed. were constant, would advance the fabric at a gradually increasing rate, the drive of each beam is of the slip-friction type, as will appear.) When one of these beams is receiving and the other delivering the fabric the former is driven and the other is disconnected from the drive and subjected to braking resistance so that tension is imposed on the fabric. Since these beams, their supporting, driving and breaking means are identical a description of one will serve for both: The beam 31 is arrangedon a square shaft 32 which at one end may be suitably journaled in the frame and at the other is received in a head-stock 33 journaled in the frame and carrying, revoluble thereon, a driving clutch member 34 and, splined thereon, a drivenclutch member 35 or fork adapted to be shifted by a bell-crank lever 36 into and out of clutching engagement with member 34. Member 34, which is also a pulley, is driven one way or the other from a pulley 37 through a belt 38, which pulley is fixed on the shaft 6" in the case of the right-hand pulley 37 Fig. 1and on a countershaft 37 in the case of the left-hand pulley, which co unters aft is itself driven from shaft 10 through the sprocket-and-chain connection 37 shown. Each belt may have adjustable tightening means, as 38 (Thus is afforded the frictiontype drive for each beam heretofore men tioned.) There is a stirrup rod 39 having a universal-joint connection 39 with the bellcrank lever 36 and it carries a cushion spring 40 and below the spring a collar 41. (The parts 36-41 are the same as in the Johnson Patent No. 1,280,232.) Mandrel 33 has a brake-head 42 encompassed by a pair of brakes 43 pivoted to the frame at 44 and (at the side diametrically opposite their pivot) one having a pivotal toggle-eI itension 45 which is connected with the other brake by a yielding and (here) adjustable connection comprisin a spindle 46 pivoted to the free end of member 45, passing freely through a hole in a stud 47 revoluble in said other brake, and having an adjusting nut 48 screwed therein and between which and stud 4'? is a spring 49.

From the free end of member 4.5 depends, pivotally, a stirrup-rod 50. i l/hen this rod is forced upwardly the toggle-means actsto force the brake into braking relation to the brake-head.

The gears 12 and 14 (from which the apron.

and two beams derive motion) are free to revolve on shaft 10, they having clutch-membcrs 12 14". Splined on this shaft are clutch members 51-52 shiftable back and forth together (to cause clutching of one or the other of the gears to the shaft while the other remains free) by the-upstanding shifters 53 pivoted at 54 (Fig. 2) in a cross-bar of the frame and having their upper or free ends bent off and connected by a link 55. The pivots 56 between these levers and the link proj ect from other levers 57. Shifting the clutch members one way or the other obviously results in reversing the direction of rotation of shaft 14 and consequently the direction of advance of apron 7 and the fabric.

At each end of the machine is an upright hand-lever 58, these two levers being p1vot-' ally "connected to move together by a rail or link 59'and each havingacrank 60 engaged between spring 40 and collar 41 on the adj oining stirrup rod 39. and a crank. 61 pivotally connected to stirrup rod 50.

Shifting of the reversing means comprising, with 5859-60, the parts whereby the clutches 5152 are shiftedand clutch-members 35 also shifted and the brakes operated, results in that one of the core-structures (which I take as here eaclivcomprehending shaft 32, beam 31 and mandrel 33) on which the fabric is now to be wound being driven by slip-friction and its brake released and the other having its slip-friction driving connection disestablished and its brake set, so that as the fabric is advancedin the new direction the goods is wound up compactly, though without imdue strain thereon, on the first-mentioned core-structure, subject to the resistance of the other or braked core-structure and hence in a state of tension.

It is usually desired (as where the goods is thin or sheer) to insure that the goods pass between the rubbing means perfectly flat, so as to avoid the formation of creases. Hence at 62 may be spreading roller of any approved type, as that set forthin my co-pending application Serial No. 130,629. This acts to spread or stretch the fabric transversely.

For a reason now to appear this devicemay be mounted on a lever 63 fulcrumed in the frame and pivotally connected to the rail 59.

In rubbing fabric it is usual to apply some liquid, as an oil or a size. At 64 is a vessel for such liquid and therein is a roller 65 dipping into the liquid and on being rotated by the. contact of the fabric therewith adapted to convey on its surface the liquid to the fabric. If it is desired that the particular liquid be conveyed to the fabric on a pass of the latter in one direction but not in the other the device 62, around which and a roller or equivalent guide 66 the fabric extends as shown in Fig. 1. will serve alternately to elevate the fabric clear of and depress it into contact with device 65 according as the fabric moves in one direction or the other.

At the opposite endof the machine is shown other means for applying liquid to the fabric,

' this operating on both face-s thereof. There bent on itself for this purpose so that each face thereof is in contact with one such brush.

The intergeared brushes'68 are rotated at very slow speed through a worm-drive 7 0 connecting the shaft ofone of them with the shaft of roller 6*, as shown in Figs. 8 and 9.

driving connection independently The parts 67: and 68 are mounted in uprights 19 forming parts ofthe bracket structures 19.

. The preferred form of rubbing roller shown in Figs. 10 and .11 has flexible fins or flaps 71, formed say of heavy canvas, and securedto the roller periphery in close arrangement around the same. In elevation each ofthese is curved withtlie peak of the curve at the middle of the roller and the curvex side facing its direction of rotation, sov that the end portions of each flap impinge against the fabric in oppositely oblique fashion, so that I wrinkles or creases.

Having thus fully described my invention,

In a machine of the class described, 'a frame, mechanism for rubbing the fabric inframe, an endless fabric advancing apron having a stretch thereof opposed to said means andyielding and between which and said means the fabric is adapted to be passed, and spaced roller-s journaled in the frame and around which the apron extends and between which said stretch is formed, in combination with reversible driving mechanism having of the apron with each roller.
